Detroit APT Metal Gasket A4721421380
The Metal Gasket seals the exhaust piping to the turbocharger to prevent exhaust leaks.
HOW IT WORKS
The gasket sits between flat, mating surfaces. The flexibility of the gasket material allows the gasket to fill the areas between the surfaces that do not match perfectly.
WHY IT MATTERS
The gasket is essential in preventing leaks. It is also necessary as a safety device as the failure of the gasket can often be a symptom that there is something else the operator may want to investigate. Gaskets are key to the proper operation of your engine.
